Car is a 72, Engine is a 71 Options

[martinef1963]

I wanted to know how would a 1.9L (BBK) 71 engine # W 0 074 343 would mix with a 72 FI system????

I've researched the FI parts and have found that the ECU that I have is Bosch 0 280 000 037 for 1972 engines, but the other associated parts, with the exception of the Throttle Switch cover both ranges (71-72 years).

I'm not at all well versed on the FI harness and it's compatibility either?

Her idling is "on roller coaster mode," sometimes she is just fine, and others she pisses me off.

I've read the Carb vs FI banter and really want to stick with the FI, but I need some real help on how this FI #$%^ works. I've read Paul Anders, Kjell Nelin articles and have done most of the parts testing.

Help anyone? (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

Do you have a 1.7L or a 1.9L?

The year of the engine vs the car doesn't have as much to do with things as the increase in displacement to a 1.9L does. It will probably not run right unless you tweak the MPS to compensate.
